Plage Activity on The NE Limb in CaK 6th April

NE-limb-cak-close-colour I could see a small patch of bright plage forming on the suns north eastern limb so decided to take a closer look at it in Calcium light at 100mm f46 using the IMX174 camera. Sadly the region didn't develop into anything more significant.
